The aim of our study is to evaluate the utility of S-MRCP in detecting carcinoma and precancerous lesions in patients with a significant family history of pancreatic adenocarcinoma. Our hypothesis is that S-MRCP is superior to traditional computed tomography (CT) or magnetic resonance imaging (MRI) in detecting early pancreatic neoplasms, and approaches the accuracy of endoscopic ultrasound (EUS).

Primary Outcome Measures:
  • Primary outcome: S-MRCP and S-EUS concordance [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    The primary outcome studied will be the concordance of S-MRCP and S-EUS. Screening will consist of two diagnostic imaging modalities. First, all patients will have S-MRCP in conjunction with contrast-enhanced MRI/MRA. All images will be analyzed by a radiologist. Within thirty days, all patients will also undergo EUS with and without secretin enhancement (S-EUS).If the S-EUS shows abnormalities, EUS-guided fine-needle aspiration will be performed. The S-MRCP and EUS image findings will be classified as benign or suspicious/malignant to determine the concordance between imaging techniques.

Secondary Outcome Measures:
  • Secondary outcome: The positive predictive value of S-MRCP [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    The secondary outcome endpoints of our study will be positive predictive value of S-MRCP,in comparison with EUS/S-EUS and ERCP, utilizing surgical pathology as the gold standard. In addition, we will also be looking at the utility of CA 19-9 and oral glucose tolerance tests.

Arms Assigned Interventions
Experimental: Secretin
Single arm (open label).
Drug: Synthetic Human Secretin
Twenty five patients will each undergo an S-MRCP and an S-EUS evaluation, at a dose of 0.2 ucg/kg per exam. Secretin, provided by the Repligen Corporation, will be administered by IV bolus injection over 30 seconds followed by a 30 second saline flush. The maximum dose of secretin will be 18.5 ucg.

Detailed Description:
Pancreatic cancer remains the fourth leading cause of cancer-related death in the United States, largely due to the lack of accurate and cost-effective screening methods. Initial screening efforts should be directed at patients with known increased genetic risk for pancreatic adenocarcinoma. About 10-20% of pancreatic cancers are considered familial or syndromic. Since pancreatic adenocarcinoma is known to progress from preneoplastic lesions, termed pancreatic intraepithelial neoplasia (PanIN), it may eventually be possible to identify and cure patients by detecting preneoplastic lesions. Traditional radiological methods lack the resolution to detect early lesions. The sensitivity and specificity of ERCP (92%,96%) and EUS (93-98%)are better, but these procedures are invasive and limited in availability. Magnetic resonance cholangiopancreatography (MRCP) has emerged as a widely-accepted alternative with comparable sensitivity to ERCP. MRCP has been further augmented by secretin stimulation, which improves visualization of the pancreatic duct as well as side branches. We will recruit 25 patients for a prospective pilot study examining S-MRCP as a screening technique in high-risk individuals. All recruited patients will undergo S-MRCP in conjunction with MRI/MRA, as well as secretin-enhanced EUS. Those patients with abnormalities on S-MRCP or S-EUS will undergo ERCP. If ERCP also shows abnormalities, these patients will be recommended total or subtotal pancreatectomy. The primary outcome that we will be studying will be concordance of S-MRCP and EUS. Secondarily, we will be measuring positive predictive value of SMRCP, in comparison with EUS and ERCP in identifying neoplasm in those patients who undergo surgical resection during this study.
